Time lapse photography taken on Mauna Kea. This is a remake with new footage included. The shots here range from about an hour on the shortest to 5 hours on the longest one. Each second in the video corresponds to roughly 6 minutes, and takes hundreds of images to compile. The lasers are used for adaptive optics and are equipped on the Keck and Gemini telescopes. As the telescopes track their targets, the laser beam sweeps with it in the sky. Passing vehicles can be seen as streaks of light on the mountain, and sometimes their reflections of the headlights can be seen on the telescopes. Passing aircraft can last around a second in the video, while meteors appear in only one frame. 1) 0:08 Submillimeter Array, looking west. Orion can be seen on the left side setting. The flashing is from me illuminating the dishes of the telescope. 2) 0:38 Same location as above, now looking east towards the rising sky. Cars can be seen moving around on the mountain, while Gemini's Adaptive Optics laser tracks the sky. From left to right, Keck I (partially visible on the edge), Infrared Telescope Facility (IRTF, perched in the background), Canada-France-Hawaii Telescope (CFHT), Gemini, University of Hawaii 88" Telescope (UH88), and United Kingdom Infrared Telescope (UKIRT) are visible. Moonshine is visible at the end. 3) 1:03 Keck II looking north. The moonshine casts a dark blue hue on the sky. 4) 1:15 Gemini AO laser in use. From left to right the telescopes are CFHT, Gemini, UH88, and <b>...</b>
